Question: A loader is used to create a 1:4 (vertical:horizontal) slope for a new embankment. The base of the slope is 10 m wide, and the desired height is 2.5 m. How much horizontal distance will the slope cover?

Answer options: ✅ 10 metres

  • 2.5 metres
  • 5 metres
  • 15 metres

Correct answer: 10 metres

With a desired height (vertical rise) of 2.5 metres, the horizontal distance covered would be 2.5 m * 4 = 10 metres.
